EDGAR Gr. NEWELL, OF GLENRIDGE, NEW JERSEY.

MACHINE FOR MAKING PACKING BANDS OR RINGS.

SPECIFICATION forming part of Letters Patent No. 752,353, dated February 16, 1904.

Application filed November 20, 1901. Serial Ho. 82,982. (No model.)

To aZZ whom it may concern:

Be'it known that I, EDGAR. Gr. NEWELL, a citizen of the United States, and a resident of Glenridge, in the county 'of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Packing Bands or Rings, of which the following is a specification.

This invention relates to new and useful improvements in machinery for automatically making paper packing rings or bands for baling, clasping, or holding together dry goods, hosiery, gloves, &c., and especially for holding together piece goods or cloth.

It embraces sundry new and useful improvements on the machine described in my former application and patented February 25, 1902, No. 693,886, and which improvements are more particularly described herein'and illustrated by the drawings referred to hereinafter.

The object of my invention is to secure greater simplicity in the making of said machine, to produce a better-finished band, and

to enable the machine to turn out. a. greater quantity of bands or rings in a given time. I attain these objects by the mechanism illustrated in the accompanying drawings, in which i Figure 1 is a plan view of the complete. machine. Fig. 2 is a side elevation of the machine. Fig. 3 is a vertical longitudinal section from the other side through thelines w w Similar reference -marks' refer to similarparts throughout the several drawings. 1

1 and l'are the feed or forming rolls of the machine, the first or top roll 1 being grooved and the under roll 1 being plain.

At 2, Fig. 4, Ishow a movable end or section of the grooved feed-roll, having a groove thereon and so arranged thatit can be moved and adjusted laterally endwise to or from the other. part of the roll on the shaft 3 (see Fig. 4:) and held by the set-screw 4, as required. By this construction the forming-groove on the rollers can be made wider or narrower, as desired, so as to take any required width of packing-band. This grooved roller 1 has circular grooves or circular recess places running around the surface of the roller at regular distances along its length, so as to allow leaves the feed-rollers'l and 1 from dropping,

bug guides it onto the pivoted knife block or be At 9 I have an endless traveling apron or belt of canvas or leather, which serves as a carrierfor carrying forward the band after it has passed through the feed or forming rollers and has been cut by the rotating knife until the finishing or. calender rollers 5 and 5 take it andpress down the edges and remove any wrinkles or imperfections therein. This carrier is drawn around the rolls 10 and 10, which rolls are driven bythe gears 11, 11, and 11', (see Figs. 1 and 2,) both carrier and its rolls being located between the feed-rollers l and 1 and the finishing or calender rollers 5 and 5' of the machine. The finishing or calender rollers 5 and 5 are driven at a little faster speed than the endless traveling apron or carrier by the pulleys 12 and 12 and the belt 13. These rollers 5 and 5 are geared together so as to run at thesame speed. This endless-belt carrier 9 is one of the special fea tures of my invention, "as it avoids'tearing the band as it leaves the knife 6 and the cuttingblock 7, which has always been a defect of knife and delivers it without defect to the finthis class of automatic machines. It carries the band as cut away from the feed-rollers and ishing-rolls 5 and 5.

At 15 and 16 I have similar tables or beds to that shown at 8, which prevent the stock or band from dropping. The table 15 takes the band from or as it passes over the pivoted block 7 and delivers it onto the carrier 9, and 16 prevents the end of the band dropping as it leaves the carrier 9, but guides it and delivers it to the finishing or calender rolls 5 and 5. By reason of this automatic action of the knife 6, the cutting-block 7, and the endless band 9, in conjunction with the tables 15 and 16, whereby the strip of paper is cut at proper length and delivered to the finishing-rollers 5 and 5 these machines are known commercially as automatic machines.

It will be noticed that the feed-rollers 1 and 1 are not both grooved. The top roller 1 only is grooved, the bottom roller 1 being plain. Thus the top roller is a forming-roller, as it forms the edge of the band in conjunction with the bottom roller, the two rollers together making practically a pair of forming feed-rollers, and to make the grooves in the top roller adjustable to any width of band which it is desired to manufacture Ihave a novel feature shown in Fig. 4:, as hereinbefore described. One end of the roller is laterally movable on the shaft 3 and can be fixed to the shaft at any desired point by the set-screw 4:. This adjustment is extremely convenient, for by it the machine can be changed at once so as to automatically manufacture any desired width of band.

At 17 I have a protecting-guide fixed alongside the endless-belt-carrier to prevent the band or stock from leaving or falling off the carrier. This device is more clearly shown in Fig. 7.

In Fig. 5 I show a mechanism for holding the feed-rollers so as to avoid any fixed vertical adjustment and allow the roller to take bands of varying thickness and to pass any uneven portions of stock without shock or tearing the band. The lower rolleris held by the block or bearing 18, which consists of two parts, the upper part being held in the guides 19 and 19 by the set-screw 20. The upper (or grooved) feed-roller is held by the block or bearing 21, and between the two bearings I have a rubber bunter or spring 22 of just sufficient thickness and tension to prevent the grooved roller from coming in contact with the lower roller 1 when the machine is running and there is no stock or band between the rollers. At 23 I have a coil-spring which rests on the box or bearing 21 and gives the top roller 1 the required pressure onto the stock or band to set the glue on the edges as they are folded over and as the band passes between the two feed-rollers 1 and 1'. This spring 23 is held'in place against the guidecap 24: and is of just sufiicient tension to give the required pressure whether the paper band be thick or thin, even or uneven. Thus the difiEiculty and trouble of vertically adjusting the rollers for different thicknesses of bands, as was formerly done in this class of machines, is entirely avoided.

My improved rollers require no means for vertically adjusting the same, but take care of themselves when made and set as herein described. Once set they require no further attention and are equally well adapted for the manufacture of thick or thin bands. In Fig. 6 is shown a cross-section of the block or bearing and the guides 19 and 19, showing the manner of holding the box in the guides by the grooves 25 and 25.

At 28 I have a slide or pivoted plate or flat spring scraper which rests on the grooved roller 1 to prevent the band from sticking to or being carried round on the roller 1 and at 28' a similar plate resting on the top finishing or calender roller 5 to serve a similar purpose At 29 I show a pin which passes through the frame of the machine into the yoke, which holds the rotating knife to prevent it moving when not in use as a guard against accidents.

The glue distributing arrangement, as shown at 26, and the edge-closing and stringinclosing guides 27 27 are the same, essentially,

as described in my United States Patent No.

693,886, as well as the rotating knife and the mechanism for operating the same.

Having thus described my invention, what I claim as new and original, and desire to secure by Letters Patent, is

1. In a machine for making paper packingbands, the combination of a pair of forming feed-rollers, a pair of calender finishing-rollers, means for cutting bands and a carrier located between said forming feed-rollers and said calender finishing-rollers, whereby the paper packing-band is delivered to said carrier after passing between said forming feedrollers, and is carried and delivered to the said calender finishing-rollers by said carrier, substantially as shown and described.

2. In amachine for making paper packingbands the combination of a pair of forming feed-rollers, a rotatable knife, having means for rotating the same; a pivoted cutting-block coacting with said knife; a pair of calender finishing-rollers; and a carrier for delivering the packing-bands as cut, from said knife to said calender finishing-rollers, substantially as shown and described.

3. In a machine for making paper packingbands, a pair of forming feed-rollers comprising a plain roller and a grooved roller, each provided with a shaft, said grooved roller consisting of two parts, one of said parts being adjustable laterally on said grooved rollershaft toward or from the other part, endwise, and means for securing the movable part of said roller in its adjusted position, substantially as shown and described.
